Salt Shift Magnetic Chassis Flusher Kit for 4WD & Trucks — Garden-Hose Ready with 1L Biodegradable Wash

Salt Shift Chassis Flusher Kit is a magnetic, garden-hose-ready system plus eco-friendly concentrate designed to flush salt, mud and grime from truck and 4WD chassis rails without lifting the vehicle.

Corrosion starts where salt and grit collect along the chassis and frame; this kit combines a secure magnetic flusher canister, a simple hose hookup and a biodegradable undercarriage wash so you can rinse and protect hard-to-reach areas quickly. Engineered in Australia for marine and off-road conditions, the flusher delivers an even spray across frame rails, suspension mounts and other vulnerable metalwork while being safe for plants and waterways when used as directed.

How does the magnetic flusher attach and stay secure during use?

The flusher uses strong neodymium magnets housed in a durable canister that clamps to the steel frame, allowing hands-free operation while you walk around the vehicle. Its low-profile shape and flexible hose swivel minimize snagging so the unit remains stable even on uneven ground.

• Powerful magnet array for firm adhesion to chassis rails
• Low-profile canister to clear suspension and brackets
• Swivel hose coupling to prevent twisting and detachment
• Hands-free positioning for consistent coverage

What does the kit include and how do I set it up?

The Salt Shift kit ships with a magnetic flusher, an adjustable concentrate mixer canister, an extension hose and 1 L (33.8 fl oz) of Chassis & Undercarriage Wash. Setup is plug-and-play: connect to any standard garden hose, clip or place the magnetic flusher to the frame, dial concentrate flow, then run water and cleaning solution through the nozzles.

• Magnetic flusher canister pre-assembled for immediate use
• Adjustable concentrate mixer for tailored dilution
• Extension hose to reach from hose point to chassis easily
• 1 L biodegradable, pH-neutral wash included

How effective is the wash at preventing corrosion and is it environmentally safe?

The included chassis wash breaks down salt, oil and grime to help remove the substances that accelerate rust; it is formulated to be biodegradable, phosphate-free and pH-neutral to reduce environmental impact compared with harsh alkalis. While no product can guarantee indefinite protection, regular use of this flusher and inhibitor reduces the buildup that leads to long-term corrosion.

• Biodegradable formula for reduced environmental harm
• pH-neutral and phosphate-free to be gentler on soil and plants
• Designed to loosen and carry away salt and road grime
• Use regularly for best long-term chassis condition

Will this fit my vehicle and work on trailers or boats?

The flusher is designed for broad compatibility with most steel chassis found on 4WDs, trucks, SUVs, trailers and many small boats with exposed frames. Its magnetic attachment requires ferrous surfaces to hold; if your frame is non-magnetic or heavily coated with insulation, alternate attachment points or temporary exposure of a bare steel area may be necessary.

• Works with most steel frame rails and crossmembers
• Ideal for trucks, 4WDs, trailers, ATVs and some boats
• Not suitable for fully non-ferrous or composite frames without metal access
• Adjust dilution based on application and material sensitivity

Who is this for: The Salt Shift Chassis Flusher Kit is made for owners who drive in coastal, winter-salt or off-road conditions and want an easy, effective way to clean and maintain the undercarriage without lifts or professional gear. It suits DIY mechanics, 4WD enthusiasts, fleet operators and anyone who needs a reliable, Australian-made solution for regular chassis flushing and corrosion prevention while keeping environmental impact in mind.
